Los Angeles Galaxy have been widely linked with a swoop for the 36-year-old, who signed a new deal with United in the summer.
Ibrahimovic opted to remain at Old Trafford, despite initial reports that a serious knee injury, which he suffered towards the end of last season, was career-threatening.
Since recovering, the forward has had minimal game time having played just five Premier League matches, one of which was from the starting spot.
According to the Daily Mail, Ibrahimovic's time with the Red Devils could be coming to an end as members of his family have been looking at properties in Beverly Hills.
The former Sweden international has not played since Boxing Day.
